MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202541028501 A) filed by Airgap Technology Pvt Ltd on March 26, 2025, for Novel Rotor Lamination With Quasi Circular Flux Barriers.
Inventor includes Sri Ranga Naga Rajesh Gudivada.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: The present invention relates to a novel rotor lamination design featuring quasi- circular flux barriers for use in permanent magnet motors. The design enhances reluctance torque while reducing the dependency on permanent magnets, leading to improved motor efficiency and cost-effectiveness. By optimizing the shape and placement of flux barriers, the invention achieves lower cogging torque and torque ripple, ensuring smoother and more stable motor operation. Additionally, the innovative rotor structure eliminates the need for stator or rotor skewing, simplifying manufacturing and assembly. This invention is particularly suited for electric vehicle motors, hybrid electric vehicles, and industrial applications where performance, efficiency, and material optimization are critical.
